During postmarketing surveillance, 52 deaths were reported in patients using cerivastatin, mainly from rhabdomyolysis and its resultant renal failure.[1] Risks were higher in patients using fibrates, mainly gemfibrozil (Lopid), and in patients using the highest (0.8 mg/day) dose of cerivastatin. Bayer A.G. added a contraindication for the concomitant use of cerivastatin and gemfibrozil to the package 18 months after the drug interaction was found.[2] The frequency of deadly cases of rhabdomyolysis with cerivastatin was 16 to 80 times higher than with other statins.[3] Another 385 nonfatal cases of rhabdomyolysis were reported. This put the risk of this (rare) complication at 5-10 times that of the other statins. Cerivastatin also induced myopathy in a dose-dependent manner when administered as monotherapy, but that was revealed only after Bayer was sued and unpublished company documents were opened.[4]
